[FIX] website_forum: fixed controller creating a new forum tha was crashing.
website_forum: fixed issue when voting. The method should work in batch. Previously to this implementation having one post with a vote bypassed the other posts without vote when called with several ids.
[FIX] mail, website_mail: specific mailing-list footer + better unsubscribe option

- remove the default footer for mail.group messages,
  replace with specific footer with archive and unsubscribe
  link
- remove the automatic addition of user signature in
  mail.group messages, as many of them will be posted
  via the mail gateway and already contain a user signature.
- make it easier to unsubscribe even when not logged in,
  as followers who have not signed up will have no
  way to login short of signing up.
- remove tests looking for user signature in mail.group posts
[FIX] mail: less confusing To: header for mailing-list posts

Many mail clients will replace the name in the To:
header with Me if the To: email matches the email
of the user. These users will see To: Me instead of
"Followers of ..." and usually believe this was a
private email from the sender to them.
But when replying they would reply to the whole list.

Fix this by explicitly forcing the To: to be the
mailing list address.
[FIX] website_mail_group: slufigy group link + spellchecking
[IMP] mail.group: set special header to disable OOF replies from MS Exchange
[FIX] ir_values: fallback when no condition

When searching for default values, if we set a condition (e.g. 'type=out_invoice'), fetch also the default values without any condition set. Thanks to the order by clause, the one with a condition have an higher priority than the one without and will not affect existing result.
This fixes default journal/currency on an invoice where the journal is retrieved in the onchange_company_id method (domain is forced). Without this patch only ir.values with a domain set will match, opw 610645
[FIX] website_sale: make the 'Ship to a different address' always available

In the backend the option 'Allow a different address for delivery and invoicing' will set the group sale.group_delivery_invoice_address to employees. However the public user is not an employee (and we don't want to change that) so does not get this group. As we don't have similar group mechanism for public user, we have no other choice than always displaying the option to have different address. opw 610118
[FIX] website_forum: prevent crash when no country

Closes #1171
[FIX] hr_timesheet: missing '&' in domain clause

To search the contracts for payroll, the domain is constructed with three clauses. Each of these clauses needs to start with a '&' to make sure they are correctly combined with the OR clause'
[FIX] hr_timesheet: handle case when has never signed in

The search may return zero results if an employee has never signed in. In this case the browse would have failed.
[FIX] crm : propagate the lead_id when scheldule other phone calls
[FIX] procurement: avoid to run multiple scheduler

Avoid to run the procurement scheduler multiple times in the same time, otherwise, they tend to interfere with each others
[FIX] sale: do not propagate context on send email

Otherwise, active_id, active_ids, active_model params are propagated, and it leads to inconsistencies.
For instances, go to Sales > Customers, choose a customer which has quotations.
On the form, hit the "Quotations and sales" Button
Choose a quotation. Hit the "send by email" button.
The template preview should be displayed correctly. Now send the email, than

 - Either, you have a traceback: There is no quotation having as id the id of the partner you chose.
[FIX] account: better error message when regenarating opening entries (opw 606923)

If we try to generate twice entries on the same fiscal year, we can get completly unrelated errors ("You can only reconcile journal items with the same partner").
With this, we make sure people will first cancel the entries before regeneraing the entries.
[FIX] sale: only propose services for pay advances

When creating an invoice from a sale order, if the user choose to invoice a fixed price (deposit), he has the possibility to choose an advance product. As described in the help message, this product should be a service product. Therefore, we add a domain so only services are displayed in the dropdown list
